The ZIP spans just 0.026 square miles in northern Baltimore County, making it one of Maryland's smallest postal zones by area. Despite its tiny footprint, Butler maintains eight ZIP+4 codes serving two streets: Falls Road and Butler Road. The community sits at the crossroads of rural carrier routes rather than city delivery routes, with three rural routes and one general delivery route serving the area.
Mail delivery here follows a rural pattern. There's no city carrier service, which is typical for communities positioned between larger towns. The 32 occupied homes represent a mix of single-family dwellings in a landscape that's more countryside than suburb. With a median age of 35.5 years, Butler skews slightly younger than Maryland's overall population.
The post office anchors a community where the median household income sits at $81,438 and median home values reach $625,000. These figures reflect Butler's position in Baltimore County's northern corridor, where rural character meets suburban prosperity. The high PO Box adoption rate isn't about lack of alternatives but about regional service patterns that extend beyond the ZIP's tiny borders.
With just two streets in the carrier route system, Butler represents one of Maryland's most compact delivery networks. Falls Road leads with two ZIP+4 records, while Butler Road has one. The simple road pattern reflects the zone's function as a rural postal hub rather than a developed residential community. These named roads—not numbered grids—preserve the area's historic rural character in northern Baltimore County.
